Hundreds of thousands of people gathered in Brazil’s largest city Sunday for its 22nd gay pride parade, which is considered one of the world’s biggest. Waving LGBT rainbow flags in a Carnival-like atmosphere, marchers paraded down Sao Paulo’s skyscraper-lined Avenida Paulista to music blasting from 18 sound trucks. Revelers of all ages, many wearing bright wigs, heavy makeup and multicolored costumes, filled more than 10 city blocks. This year’s parade focused on Brazil’s national elections scheduled for October. The theme was “Power for the LGBT — Our Vote, Our Voice,” said Claudia Regina, president of the gay rights group that organized the event. Regina said on the event’s official Facebook page that the objective “is to alert the gay community to the importance of choosing its candidates carefully.”
